    </UL>
</LI>
<LI>Minimum required version of CMake to build Geant4 is 3.3.
    User applications can still use CMake 2.8.X or above for configuration
    and compilation. It is however recommended to migrate to CMake 3.3 or 
    above for its improved support of C++ compile and target features.</LI>
</UL>

<P> </P>
<B>Geometry</B>
<P> </P>
<UL>
<LI>A new minor release of the GDML schema, GDML-3.1.3, is used,
    supporting optional export of physical volumes copy-numbers and
    geometrical regions dump.
    The new schema is fully compatible with old schema versions
    and schema validation thorugh network is already activated against it.</LI>
<LI>Optional adoption of the 
    <A HREF="https://cern.ch/aidasoft/USolids">Unified Solids Library</A>,
    can now be achieved after installation of the library as external
    package.</LI>
</UL>

<P> </P>
<B>Electromagnetic and optical physics</B>
<P> </P>
<UL>
<LI>Updated Goudsmit-Sounderson multiple scattering model for e+- 
    can be tested in various applications. A new electromagnetic (EM) 
    physics constructor G4EmStandardPhysicsGS is provided
    for that.</LI>
<LI>For applications which are using C++ interface to define parameters 
    of EM physics, it is recommended to switch from usage of the
    G4EmProcessOptions class to the G4EmParameters class. 
    This will guarantee coherent parameters definition also for multi-thread
    setup.</LI>
<LI>Public methods and corresponding UI commands have been added to
    activate PAI, MicroElec, or DNA models in one or more Geant4 regions.</LI>
<LI>In all ionisation processes which simulate energy loss along step
    the models' lowest energy limits, which force full energy deposition at
    a step independently on the material, are reviewed. A coherent and common
    approach is introduced, allowing the user to set the value of this limits
    via UI commands or the new interface class G4EmParameters. 
    Introduction of a lowest energy allows to remove hidden tracking cuts
    and limits from elastic scattering and ionisation models.
    For very low-energy simulations these lowest energy limits may be set
    to zero.</LI>
<LI>Added alternative Geant4-DNA physics models for liquid water.</LI>
<LI>The data file G4EMLOW-6.48 should be used.</LI>
</UL>

<P> </P>
<B>Hadronic physics</B>
<P> </P>
<UL>
<LI>The new data sets <TT>G4PhotonEvaporation-3.2</TT>, 
    <TT>G4RadioactiveDecay-4.3</TT> and <TT>G4ENSDFSTATE-1.2</TT> 
    should be used.</LI>
<LI>The environment variable <TT>G4ENSDFSTATEDATA</TT> must be set
    to <TT>G4ENSDFSTATE-1.2</TT>.</LI>
<LI>The <TT>NeutronHP</TT> module has been replaced by <TT>ParticleHP</TT>:
    no change in the user code is required.</LI>
</UL>

<P> </P>
<B>Data Sets</B>
<P> </P>
This release introduces new data set versions.
Please see the corresponding details in
<A href="#data-notes">Section 9</A> of this document.
<UL>
<LI>New data set versions: <TT>G4EMLOW-6.48, G4ENSDFSTATE-1.2,
    G4RadioactiveDecay-4.3, G4PhotonEvaporation-3.2</TT>.</LI>
<LI>The G4ENSDFSTATE data set has now become mandatory, therefore it is
    required to have it installed and the appropriate environment variable
    <TT>G4ENSDFSTATEDATA</TT> for its path to be set.</LI>
<LI>In order to use <TT>ParticleHP</TT> for charged particles
    (protons, deuterons, tritons, He3 and alphas), an optional data
    set <TT>G4TENDL-1/0</TT> is required, and should be downloaded in
    addition from the Geant4 web site.</LI>

<H2>4. New Developments and Capabilities </H2>

<B>Analysis</B>
<UL>
<LI>Added "batch plotting" facility.</LI>
<LI>Added classes for users parameters management.</LI>
<LI>Added ability to send/receive histograms through MPI.</LI>
</UL>

<B>Geometry</B>
<UL>
<LI>In this release, an option allows an installation to use the
    <A HREF="https://cern.ch/aidasoft/USolids">Unified Solids Library</A>
    primitives, to replace the original Geant4 solids, as in the
    previous release. The path to an external installation of the USolids
    library (VecGeom version <TT>v00.01.00</TT>) should be specified.
    See the associated instructions file for configuration and installation.</LI>
</UL>

<B>Electromagnetic physics</B>
<UL>
<LI>New UI commands and C++ interfaces to define parameters 
    of EM physics are now provided. PAI models may be enabled per particle type
    and detector region on top of any EM physics configuration.
    For example, the UI command <TT>"/process/em/AddPAIRegion all Tracker"</TT>
    defines PAI model for all charged particles in Tracker region.
    MicroElec models for the Silicon and set of DNA default models for the liquid 
    water may be also enabled via UI commands and C++ interface.</LI>
<LI>In all ionization processes which simulate energy loss along step
    a lowest energy limit is introduced, which forces full energy 
    deposition at a step independently on material. Its value may be 
    changed via a new UI commands or through the interface class
    G4EmParameters. The default value is <TT>1 keV</TT>, for Opt3, Opt4,
    Livermore, and Penelope physics constructors lowest e+- energy is
    <TT>100 eV</TT>.</LI>
<LI>By default lateral displacement sampling is disabled for muons, hadrons,
    and ions. To enable lateral displacement a new UI command should be used:
    <TT>"/process/msc/MuHadLateralDisplacement true"</TT>.</LI>
<LI>G4UrbanMscModel has been updated: e+ corrections are added and a new
    optional algorithm to sample lateral displacement is introduced.
    The new lateral displacement sampling is used only in Opt3, Opt4,
    Livermore, and  Penelope EM physics constructors.</LI>
<LI>A new implementation of the Goudsmit-Saunderson model for multiple-scattering
    is now used for e+- below 100 MeV in the G4EmStandardPhysicsGS
    constructor. It is available in the experimental physics-list
    FTFP_BERT_TRV.</LI>
<LI>The single scattering model with Mott corrections may be enabled in the
    G4EmStandardPhysicsSS physics constructor using the new UI command:
    <TT>"/process/msc/UseMottCorrection true"</TT>.</LI>
<LI>Ion/ion stopping power tables have been updated using new 
    computations of A. Schinner.</LI>
<LI>Introduced new G4LowEPPolarizedComptonModel for simulation of the
    Compton scattering of linear polarized gamma.</LI>
<LI>Full Auger atomic de-excitation cascade simulation may be enabled 
     via the new UI command: <TT>"/process/em/augerCascade true"</TT>.</LI>
<LI>The usage of the more accurate atomic transition energies (Bearden data)
    can be enabled via the UI command:
    <TT>"/process/em/fluoBearden true"</TT>.</LI>
<LI>Added alternative Geant4-DNA physics models for liquid water
    and extra DNA physics constructors.</LI>
</UL>

<B>Hadronic physics</B>
<UL>
<LI>Improved simulation of low-energy, evaporated nucleons by Fritiof model
    coupled with Precompond-de-excitation model.
    It affects the energy response in hadronic showers: the visible energy
    in simplified calorimeters increases in not heavy absorber materials,
    e.g. Iron and Copper.</LI>
<LI>A new model for nuclear gamma de-excitation model has been introduced.
    It affects the lateral shapes of hadronic showers: narrower showers
    are produced, especially for heavy absorber materials.</LI>
<LI>The model <TT>NeutronHP</TT> has been merged into the <TT>ParticleHP</TT> 
    model, which now extends the treatment of low-energy neutrons (below
    <TT>20 MeV</TT>) to charged particles: proton, deuteron, triton, 3He and
    alpha, with energies up to <TT>200 MeV</TT>.
    Note: users should be careful when using this model for charged particles,
    for various reasons: validation is not yet completed; only the inelastic
    interactions are included in this model, while the elastic interaction
    is treated independently by other Geant4 models; the TENDL data library is
    deployed, which means that ENDF VII(.r1) evaluated data is used only for
    the few cases where it is available, while, in all other cases,
    the data from TALYS nuclear model is utilized, which can lead to
    large uncertainties.
    In order to use ParticleHP for charged particles, the optional data set
    G4TENDL-1.0 is required.</LI>
<LI>Substantial revision of the Radioactive Decay model:
    now using G4UAtomicDeexcitation to handle fluorescence and Auger electrons;
    improved energy conservation for IT and EC modes to order <TT>30 eV</TT>
    by using approximate shell energy method of A. Zoglauer;
    adapted to changes in particle category by providing a mass defect check
    between parent and daughter nuclei; removed dependence on local
    isotope table in favor of that in G4NuclideTable.</LI>
</UL>

<B>Particles</B>
<UL>
<LI>Mass width is taken into account in Phase Space Decay when daughter
    particles are resonant particles; dynamic mass is given to daughter
    particles according to the Breit-Wigner formula.</LI>
</UL>

<B>Physics Lists</B>
<UL>
<LI>New experimental EM physics constructors: G4EmStandardPhysicsGS, 
    G4EmStandardPhysicsWVI, G4EmSTandardPhysicsSS.</LI>
<LI>Replaced the Chips neutron elastic cross-section with NeutronElasticXS
    one in all (non-HP) physics lists.</LI>
<LI>The Glauber-Gribov kaon inelastic cross-sections are used in all physics lists
    (instead of either Chips or Gheisha cross-sections). </LI>
<LI>In the QBBC physics list, the upper limit of Bertini has been reduced
    from <TT>12</TT> to <TT>4 GeV</TT>.</LI>
<LI>The <TT>FTFP_BERT_TRV</TT> physics list uses now the standard EM option
    with the new Goudsmit-Saunderson multiple scattering model 
    (i.e. G4EmStandardPhysicsGS). Moreover, the transition region
    between Bertini and Fritiof models has been reduced from <TT>[3, 12] GeV</TT>
    to <TT>[2, 4] GeV</TT>.</LI>
<LI>The physics list <TT>QGSP_BIC_AllHP</TT> uses the <TT>ParticleHP</TT>
    model for charged particles (p, d, t, 3He, alpha) below <TT>200 MeV</TT>.
    Note: this requires some optional data libraries, which the user needs
          to download from the Geant4 web site.</LI>
</UL>

<B>Run</B>
<UL>
<LI>New UI command for running in multi-threading mode by forcing the
    random generator engine to use a specified state (stored in a file)
    for each event. This allows to test strong reproducibility in pure
    multi-threading mode.</LI>
<LI>Increased granularity of MT methods to allow easier subclassing
    of run-manager classes and ease integration with external frameworks.</LI> 
</UL>

<B>Visualization and Interfaces</B>
<UL>
  <LI>New dedicated thread for visualization in MT mode</LI>
  <LI>New commands for multithreading:
      <UL>
      <LI><TT>"/vis/multithreading/actionOnEventQueueFull"</TT>: when event
          queue for drawing gets full, wait or discard events.</LI>
      <LI><TT>"/vis/multithreading/maxEventQueueSize"</TT>: defines maximum
          event queue size.</LI>
      </UL></LI>
  <LI>Added viewer menu button in Open Inventor for PDF output.</LI>

<H2>5. Expected effects on physics and computing performance</H2>

<B>Electromagnetic physics</B>
<UL>
<LI>Expected reduction of memory per thread in multi-treaded mode.</LI>
<LI>Due to increased precision in some models, the measured CPU performance
    for some cases of high energy EM shower in HEP calorimeters
    is ~1% slower with respect to the previous Geant4 release.</LI>
</UL>

<B>Hadronic physics</B>
<UL>
<LI>Hadronic showers have changed in two aspects: increased visible energy
    in not heavy absorber materials (e.g. Fe and Cu); 
    narrower lateral showers in heavy absorber materials (e.g. W and Pb).
    The change in energy response is mostly due to the development in the
    formation of the excited nuclear remnant in the Fritiof model.
    The change  in the lateral shape is mostly due to the new model for
    nuclear gamma de-excitation.</LI>
<LI>In some cases simulations of hadronic showers in HEP calorimeters
    are faster up to 5% with respect to the previous Geant4 release.</LI>

<A NAME="conf-notes">
<H3><I>Configuration</I></H3></A>
<UL>
<LI>Use CMake Compile Features to setup C++ Standard.
    Removed setup of C++ Standard selection via compiler version checking.
    Created list of compile features required by Geant4.
    Maintain GEANT4_BUILD_CXXSTD option to allow user to choose between
    C++11 and C++14 standards. When newer standard is chosen, require that
    compiler supports at least one feature from that standard, and add all
    supported features of that standard to the required list.
    Updated setting of flags and standard used to obtain information from
    compile features.</LI>
<LI>Always use libc++ with Apple Clang so that std-supporting library is
    used for C++11 mode on older Mac systems where libstdc++ is the default.</LI>
<LI>Migrate output directories for build products to use same layout as
    install tree. For single mode generators (Makefiles/Ninja), products
    are output to a 'BuildProducts' subdir of the main binary dir which
    holds bin/lib directories as derived from requested install dirs.
    With multimode generators (Xcode/VS), 'BuildProducts' holds an extra
    directory layer, one per build mode, under which the same bin/lib
    structure is used.</LI>
<LI>Updates for migration to CMake >= 2.8.12. Use generator expressions in
    setting of per-mode compile definitions for Geant4 libs.</LI>
<LI>Removed -no-gcc in CMAKE_CXX_FLAGS when using Intel compiler, as gcc
    interoperability is required for use of C++11 features in cxxlib.
    Removed -i-dynamic from LDFLAGS, no longer supported.
    Corrected checking of Intel compiler to use better CMAKE_CXX_COMPILER_ID
    variable.</LI>
<LI>Only allow use of system USolids, i.e. external installation of the
    package.</LI>
<LI>Updated Apple Clang detection to work on Xcode-7.</LI>
<LI>Correction to allow for both static and shared libs to be built on
    Windows.</LI>
<LI>Added new GEANT4_USE_FREETYPE option (OFF by default), to allow user to
    enable Freetype support in analysis library.
    Added export of TOOLS_FONT_PATH to environment when Freetype support is
    enabled, pointing to the fonts/ subdirectory of Geant4's share directory.
    Added TOOLS_FONT_PATH to test environment when Freetype support enabled.</LI>
<LI>Updated FindROOT.cmake script to provide compatibility with Root-6 and
    allow usage of ROOTConfig.cmake, if available.</LI>
<LI>Changed default build mode for single config generators to RelWithDebInfo
   to match testing system and UNIX conventions.</LI>
<LI>Added new MSVC only option GEANT4_BUILD_MSVC_MP, defaulting to OFF.
    When ON, it prepends /MP to CMAKE_CXX_FLAGS to enable file level parallel
    compilation on Windows.</LI>
<LI>Allow user to force search for Qt4 only when GEANT4_USE_QT is selected.
    Requested on HN User Forum #1766.</LI>
<LI>Put CLHEP version 2.3.1.x as the minimum required.</LI>
<LI>Updated data-sets versions.</LI>

<H3><I>Run</I></H3></A>
<UL>
  <LI>New functionalities for MT:
  <UL>
  <LI>Added new method <TT>G4WorkerRunManager::DoWork()</TT>, called by
      <TT>G4MTRunManagerKernel::StartThread()</TT> to process requests of new runs
      from kernel.</LI>
  <LI>Moved setting of pin affinity from <TT>G4MTRunManagerKernel::StartThread()</TT>
      to G4WorkerThread.</LI>
  <LI>Corrected handling of deletion of worker run-managers.</LI>
  <LI>G4MTRunManager: removed explicit initialization of Bertini Cascade
      (now done in Bertini module).</LI>
  <LI>Replaced calls to IsWorkerThread() by <TT>G4Threading::IsMasterThread()</TT>.</LI>
  <LI>Fixed issue for random-number strong-reproducibility in MT mode.
      A new UI command has been introduced to allow to run in MT mode
      by forcing the random generator engine to use a specified state
      (stored in a file) for each event:
      <TT>"/random/resetEngineFromEachEvent true"</TT>. It looks for
      the files <TT>runXevtY.rndm</TT>, where <TT>X</TT> is the
      run-number (starting from 0), and <TT>Y</TT> is the event-number
      (starting from 0): if these files are not found, then the reseeding
      is ignored and the run proceeds as usual.
      This command allows to test the strong reproducibility in pure MT mode,
      e.g. to re-run a single event with the starting random engine status
      <TT>G4Worker3_run0evt5.rndm</TT> it is enough to rename (or copy) it
      as <TT>run0evt0.rndm</TT> and use the above UI command.
  </LI>
  <LI>Invoking <TT>G4ParticleTable::DestroyWorkerG4ParticleTable()</TT> in
      G4WorkerRunManagerKernel destructor to cleanly delete thread-local
      particle dictionaries.</LI>
  </UL></LI>
<LI>Other changes (non MT related):
  <UL>
  <LI>Added new G4MultiSensitiveDetector functionality.</LI>
  <LI>G4VUserPhysicsList: lookup for default-world-region in G4RegionStore
      instead of accessing the store at index 0. It's not always guaranteed
      the default world region is the first element in the store!</LI>
  <LI>Added MixMaxRng to the list of possible engines to use in
      <TT>G4UserWorkerThreadInitialization::SetupRNGEngine()</TT>.

    <UL>
    <LI>Now adopting dedicated thread for visualization in MT mode.</LI>
    <LI>New interface in G4VViewer for multi-threading.</LI>
    <LI>Re-implemented graphics system fallback strategy. A graphics system may
        have more than one nickname. This is used for finding a fallback graphics
        systems when, for example, a Qt session is requested but the user has not
        instantiated a Qt session, or when interactive graphics systems are
        prohibited, as in batch mode.<BR>
        This allows the user to run an application
        that is fully configured with all available graphics systems, even under
        circumstances for which the primary graphics system is inappropriate. For
        example, it allows one to make a image with these commands in a batch
        macro: <TT>"/vis/open OGL"</TT>, <TT>"/vis/drawVolume"</TT>,
